  • The existing defect management is focused on step before closing work, a builder preliminary research and tenant preliminary research. Each step is not related. And the existing study on defect management mainly classify into work type and defect type according to work type. This study divide into defect part. Also this study propose PDA based web and 3DCAD for improving method of existing defect management.

  • Purpose: The reconstruction of oropharyngeal defect after cancer surgery is very difficult because of their complicated structure and the functional importance to prevent velopharyngeal incompetence. In this article we investigated affecting factors of velopharyngeal function after reconstruction and a fundamental rule of reconstruction for saving their functions such as swallowing, speeching and breathing. Methods: We classified 18 patients into three group under Kimata's grouping. Type I defect(6 patients) was healed by primary closure or secondary intention. In Type II or III defect, two operation methods were used - the folded flap(8 patients) and modified Gehanno method(4 patients), which include a lateral-posterior pharyngeal rotation-advancement flap. We evaluated wound dehiscence between the flap and the soft palate, speech intelligibility using Hirose's method, regurgitation during oral feeding, and hypernasality. Results: Most of type I or II defects patients recovered satisfactory velopharyngeal function. But, in patients with type III defects we found wound dehiscence, worse speech function, and common velopharyngeal incompetence. Conclusion: The large defect size and presence of wound dehiscence are major factors of postoperative velopharyngeal function. We conclude that folded flap or modified Gehanno method is a good reconstructive operation method for broad contact between the flap and defect site, preventing wound problem.
